Failed Root Canal Treatment in North Finchley

A failed root canal does not always bring strong pain right away. Sometimes the signs are subtle. Seek an assessment if you notice persistent or recurring symptoms in a tooth that was treated before. Common indicators include a dull ache, sharp pain when you bite, tenderness or swelling in the nearby gums, or a small pimple-like bump (a sinus tract) appearing on the gum. Discoloration of the tooth can also be a sign. Do not ignore these symptoms, as the underlying infection could spread and damage the surrounding bone. Our practice offers same-day consultations for urgent cases during office hours to determine the cause of your discomfort.

Retreatment is a careful procedure that gives your tooth a second chance. First, you will have a 60-minute consultation where we use a 3D CBCT scan to get a detailed view of the root canals and identify the problem. During the treatment appointment (typically 90-120 minutes), Dr. Reddy will carefully remove the old filling material under high magnification using a dental operating microscope. The canals are then thoroughly cleaned, disinfected, and reshaped before being sealed with a new biocompatible filling. Finally, after the procedure, you will be referred back to your general dentist to have a new, permanent crown placed to protect the tooth. The success rate for retreatment is high, generally between 75-90%.

A patient from North Finchley came to us with a dull ache in a molar treated five years earlier. An X-ray was inconclusive, but our 3D CBCT scan revealed a missed, narrow canal that held bacteria. The retreatment took a single 90-minute session. We located and cleaned the missed canal using the microscope. Within a week, his symptoms were gone, saving a tooth that might otherwise have been extracted.

After retreatment, you may notice some mild to moderate tenderness for three to five days. This is usually manageable with over-the-counter painkillers like ibuprofen. Stick to a soft food diet for the first few days and avoid chewing directly on the treated tooth until the final crown is fitted. You can brush and floss as normal, but be gentle around the area. It is essential to attend your follow-up appointment with your general dentist to have the permanent restoration placed, as this protects the tooth from fracture. Red flags during office hours (Mon/Wed/Fri 9-5, Tue/Thu 11-7) include severe, throbbing pain not controlled by painkillers, increasing swelling inside or outside your mouth, or a fever above 38°C.

When a root canal fails, retreatment is usually the first and best option because it aims to save your natural tooth. However, it is not the only choice. Apicoectomy (Root-End Surgery): If the infection sits at the tip of the root or if retreatment is not possible, a minor surgery called an apicoectomy may be recommended. This involves removing the root tip and sealing the end. Extraction and Dental Implant: If the tooth is badly damaged, cracked, or there is extensive bone loss, extraction may be the only viable solution. The missing tooth can then be replaced with a dental implant, which functions like a natural tooth but is a more invasive and costly procedure starting from £2,500. During your consultation, we will discuss the pros and cons of each option based on your specific clinical situation.

To make an informed choice about your dental health, here are key questions to ask any provider, whether it is us or another practice serving North Finchley: - What is the likely cause of the failure of my first root canal? - What is the success rate for retreatment in my specific case? - Do you use a dental operating microscope and 3D CBCT scanning for diagnosis and treatment? - What are the full costs involved, including the consultation, treatment, and final restoration? - What are the alternatives if retreatment is not successful? - What is your experience with complex retreatment cases like mine?

The cost of root canal retreatment is higher than an initial root canal because the procedure is more complex and time-consuming. The final fee depends on the tooth's location and the complexity of the case. A full, transparent quote will be provided after your initial consultation and 3D scan.
